Celebrate a third birthday with preschool toys that are designed to encourage new abilities! Between the ages of three and four years old, promote self-expression with toys for building, arts-and-crafts activities, and role-play sets. Or offer jigsaw puzzles, peg puzzles, and magnetic activities in age-appropriate themes for an exciting new challenge! This is also a perfect time to introduce a collection that can grow through the years, such as a dollhouse set, train tracks, or costume/role play closet.
